IMPROVEMENT IN MANUFACTURING ENVELOPES.

The Schedule referred tu 1n these Letters Patent and. making part of thesame.,

'u au' whom it may concern Beit known that I, JAMES BALL, ofthe city,county, and State of New York, have invented a new and irnproved Sheetfor Ont-ting out Envelopes; and I 'do hereby declare the following tobeafnll, clear, and exac t description thereof, which will enable thoseskilled in the art to make and use. the same, reference being!I had tothe accompanying drawing forming part of this specil'ication, whichdrawing represents a plan or tace view of a sheet of paper cut outaccording to this invention.

In cutting out envelopes-the first operation usually is to cut a roll ofpaper up into sheets, each sheet-large enough for sixteclu'niore orless, envelope blanks. lhe form ot' these 'sheets is'either square ordiamond-shape, but in all cases known to me the edges ot' the sheetshave heen rectilinear, and I have found that by cutting the 4sheets withrecessed or pectinated ends or edges, a great saving ot' paper can be"'etiected.

It' the sh'eets are cut with square edges it requires under the bestpossible management, thirty inches in length (the width ot' the sheetbeing that of the roll from which the sheets are cut) for sixteenenvelopeblanks Otordinary letter size, bnthycutting the sheets withpectinated or scalloped edges according to-xny invention, onlytwenty-seven inches in length :nerequired for sixteen envelopes of thesaine s ize, and consequently a very material saving of' paper is et'-fected.v t I In the dra\ving i The letter A designates a vsheet of papercut out with scalloped ends o b, the scallops being composed ofangular'recesses formed in succession across the sheet, those ofthe edgea ,being reverse to those of the edge 71, so that no paper is wasted.

.My invention is hereillustratcd in connection with rholnbshaped blanks,and una sheet of this kind the, pattern for an envelope-blank can he soadjusted that sixteen rhon'ib-slutped envelopes can be cutont from thesaine, and I llavefoniid that l can save threeinches ot' paper on cachsheet of sixteen envelopes, as compared with the old method ot cutting.

The amount of paper saved hy my invention of course varies according tothe size ot' the envelopesA to be cut out, but lny experience snows thatin the factory where l ain employed, and where we have cut up forsuccessive days as much as forty-tive thousand yards of paper per dav, Ihave heen enabled to etl'ect a saving offour thousand live hundred vardsper day, since forty thousand tive hundred yards of paper when cutaccording to my' invention, will produce as many envelopes astorl1y-tive thousand yards out in the old u v. v

In order to cut out niy sheets with the requisite accuracy and despatch,I have constructt-ul 'a cuttingmachine,`hy lneans of which sheets -withscalloped edges can be cut with great facility, hut lV do notre-'strictmyselt' to any mode of forming such edges or ends ot' the sheets.vWhat I claim as new, and desire to secure hy Letters Patent, is

'lhe sheet A for envelope-blanks, formed with Vscalloped ends a andb,`thc scallops made with angular recesses in succession across thesheet, when those of the edge a are reverse to those ofthe edge Zr,substantially as herein shown and described.,
